Referring to fig. 1 and 8, the fourth camera 5 is disposed at a position close to the lower side of the apparatus body 1, and the optical axis direction of the fourth camera 5 is inclined by a certain angle α to the right below with respect to the horizontal line-of-sight direction of the wearer2；
The optical axis of the second camera 3 and the optical axis of the third camera 4 are located on the same horizontal plane, and the first camera 2 and the fourth camera 5 are located at the intermediate position between the second camera 3 and the third camera 4.
Here, the optical axis direction of each camera described above refers to a normal direction of the camera.
Preferably, the first camera 2 is located directly above the fourth camera 5.
Preferably, the viewing angle normal of the second camera 3 is rotated to the left and right by an angle of-22.5 degrees to +22.5 degrees.
Preferably, the viewing angle normal of the third camera 4 is rotated to the left and right by an angle of-22.5 degrees to +22.5 degrees.
By limiting the angle of rotation of the second camera 3 and the third camera 4 to the left and right sides in the normal direction, the maximum horizontal view can be obtained, and the blind area can be minimized.
After the 4 cameras are placed at proper positions, the respective visual fields of the 4 cameras are combined, namely, the outermost boundary of the area visible by the 4 cameras in the placing mode is shown, for the convenience of observation, a sphere and the combined boundary are combined to form a visual field similar to a hemisphere, and the radius of the hemisphere can be infinitely enlarged.
Referring to fig. 6, a region a is a blind region formed by the crossing of the views of the first camera 2, the second camera 3 and the third camera 4;
the B area is a blind area formed by the crossing of the vision fields of the second camera 3, the third camera 4 and the fourth camera 5;

through the camera layout scheme, the range of the synthetic vision field is large, and the minimization of the blind area can be realized.
Preferably, the second camera 3 and the third camera 4 are used for head 6dof tracking.
Considering that the FOVs of the 4 cameras need to be close to or more than 180 degrees superimposed in the vertical direction, it is necessary to set the vertical views of the first camera 2, the second camera 3, the third camera 4, and the fourth camera 5 to be more than 70 degrees.
Preferably, the photosensitive chips of the first camera 2, the second camera 3, the third camera 4 and the fourth camera 5 all adopt a rectangle shape, and the length: the width is 4:3 or 3:2 with equal proportion size, and the size of the camera is matched with the size of the photosensitive chip of the existing camera manufactured in large scale, so that the camera is convenient to purchase and apply, and the cost is reduced.
Preferably, the first camera 2, the second camera 3, the third camera 4 and the fourth camera 5 are respectively and fixedly connected with the apparatus body 1, and of course, each camera may also be detachably connected with the apparatus body 1 through a connecting member, for example, a mounting hole is provided at a corresponding position on the apparatus body 1, and the cameras are fixed in the mounting hole through a clamping member, and the like.
The following explains the synthetic view principle of 4 cameras:
referring to fig. 1 and 7, the normal directions of the second camera 3 and the third camera 4 in the middle are preferably set; in this embodiment, the second camera 3 and the third camera 4 are used for head 6dof tracking, and based on a high-pass platform, it is specified that the second camera 3 and the third camera 4 must be horizontally placed, and the normal viewing angles of the second camera 3 and the third camera 4 are both rotated by 22.5 degrees to the left and right at maximum.
The resultant horizontal viewing angle CFOV _ H- β can be calculated as the relationship in the figure1+β2+β3Wherein, β3The angle of rotation is normal to the left and right sides for the visual angle of second camera or third camera, in addition also can see that, the distance D of the visual angle crossing point of second camera 3 and third camera 4 to the front surface of equipment body 1 is the blind area size. In general, in order to obtain the maximum combined horizontal viewing angle HCFOV, it is considered to use a camera having a relatively large horizontal viewing field in addition to driving the second camera 3 and the third camera 4 by 22.5 degrees to the outside. This allows both a maximum HCFOV and a minimization of the dead zone D.
Referring to fig. 1 and 8, since the vertical FOV of a single camera is typically significantly smaller than its horizontal FOV, the vertical composite VCFOV needs to be maximized by using the vertical FOVs of the 3 cameras, in this embodiment, the orientations of the middle second camera 3 and the third camera 4 have been determined, and when the upper first camera 2 and the lower fourth camera 5 are placed, the principles of maximizing the composite VCFOV and minimizing the dead zone are also based on the principle of maximizing the composite VCFOV1And α of the first camera 22It is easier to achieve a total 180 degree vertical synthetic FOV which benefits from this particular camera layout of the present invention.
Adopt above-mentioned technical scheme, the wearable equipment of VR that this application provided, the technological effect who has:
the current 6dof of hand is generally through controlling a pair of handles of handheld, is provided with the luminous point that can be caught by the camera on the handle, through the location of luminous point on the handle of different cameras to specific gesture, and then can discern position and position information of handle under corresponding gesture through equipment body and camera to reach the effect of pursuing the hand action. In the layout mode of the product, the respective vision fields of the 4 cameras are synthesized to form a vision field similar to a hemisphere, the radius of the hemisphere can be infinitely enlarged, and then, the layout of the 4 cameras is utilized to realize that a larger synthesized vision Field (FOV) is achieved by using less cameras; and further the effect that 5 or 6 cameras are adopted in the current product and other layouts are achieved can be achieved.
It should be noted that, the specific processing method for identifying and positioning the light-emitting point on the handle by the apparatus body and the cameras belongs to the prior art, and therefore, the processing method is not described in the technical solution of the present application.
